摘要
将钢渣微粉以不同的掺量掺入水泥中进行砂浆实验与水化热实验,研究钢渣微粉潜在胶凝性的发展。结果表明:钢渣微粉的掺入会降低水泥的胶凝性能,但钢渣微粉水化后期的潜在胶凝性比水泥高。钢渣微粉可以提高砂浆的流动度、折压比,大幅降低水泥的水化热。
In order to study the development of the potential cementitious property of the steel slag powder,the mortar experiment and the hydration heat experiment were carried out by adding the steel slag powder into the cement with different amount.The results show that the addition of steel slag powder can reduce the cementitious property of cement,but the potential cementitious property of steel slag powder in the later stage of hydration is higher than that of cement.The fluidity and compression ratio of mortar can be improved by using steel slag powder,and the hydration heat of cement can be greatly reduced.
